| Abstract: | The impact response and failure mechanism of the composed ceramic/composite armour are simulated numerically by use of the solution method to contact-impact problems. Emphasis is put on the searching and determination of the contact-impact interface between the projectile and armour, the algorithm for the contact-impact force calculation, the establishment of failure criterion and its implementation strategy. The computational results are compared and agreed well with those data resulted from test. |
